It's estimated that around 3.5 million Bitcoins are lost, but recently a miner from 2010 sold about 2,000 Bitcoins, suggesting that this number might be lower. Many early holders will likely pass their Bitcoins as inheritance or start using them when the price hits 1 million dollars. The original Bitcoin community, known as OGs, likely didn’t lose their assets. Just reading Bitcoin Talk shows that this group had ideas and thoughts far ahead of their time.
